适用于appr.tc的原生Android应用 _Android应用

非淡泊无以明志，非宁静无以致远。这篇文章主要讲述适用于appr.tc的原生Android应用相关的知识，希望能为你提供帮助。
从几个星期以来，我正试图通过使用apprtc在本机android应用程序（https://github.com/njovy/AppRTCDemo）和浏览器之间建立websession。当使用appr.tc作为room-server url时，该应用程序运行良好。我已经在Ubuntu上设置了apprtc项目，我可以在Ubuntu机器上的浏览器和我的移动设备的浏览器之间创建一个会议。但是当我尝试在ubuntu上的浏览器和应用程序之间建立连接时，我总是收到以下错误：

Room IO error: java.io.IOException: Non-200 response when requesting TURN server from https:// networktraversal.googleapis.com/ v1alpha/iceconfig?key=none : HTTP/ 1.1 400 Bad Request

Error-Screenshot
错误消息中提到的URL在src / app_engine / constants.py（https://github.com/webrtc/apprtc/blob/master/src/app_engine/constants.py）中定义。但我不知道如何处理它

# TODO(jansson): Remove once AppRTCDemo on ios supports ICE_SERVER. TURN_BASE_URL = 'https://computeengineondemand.appspot.com' TURN_URL_TEMPLATE = '%s/turn?username=%s& key=%s' CEOD_KEY = '4080218913'ICE_SERVER_BASE_URL = 'https://networktraversal.googleapis.com' ICE_SERVER_URL_TEMPLATE = '%s/v1alpha/iceconfig?key=%s' ICE_SERVER_API_KEY = os.environ.get('ICE_SERVER_API_KEY')CALLSTATS_PARAMS = { 'appId': os.environ.get('CALLSTATS_APP_ID'), 'appSecret': os.environ.get('CALLSTATS_APP_SECRET') }

那到目前为止我做了什么？（这几乎是apprtc https://github.com/webrtc/apprtc#deployment的部署过程）

从git下载最新版本的webrtc

安装了npm，nodejs和grunt

使用grunt构建来构建源代码

下载，安装和配置的对撞机（对撞机在rtc上运行：8089） 4.1我必须在workspace / src / collidermain中更改main.go from：var roomSrv = flag.String（“room-server”，“hxxps：//appr.tc”，“房间服务器的起源”） to：var roomSrv = flag.String（“room-server”，“hxxp：// rtc”，“房间服务器的起源”） 4.2还在src / app_engine / constants.py中将WS_INSTANCE_HOST_KEY更改为碰撞者adresse rtc：8089

我安装了CoTurn并添加了一个看起来像的turnserver.conf 监听端口= 3478 听-IP = 192.168.178.20 用户= RTC：的WebRTC 证书= /家庭/ RTC /工作/ src目录/撞机/ CERT / cert.pem p键= /家庭/ RTC /工作/ src目录/撞机/ CERT / key.pem

Collider运行在192.168.178.20:8089（或rtc：8089）和转发服务器192.168.178.20:3478。在turnserver.conf中定义的凭据：Username = rtc，Password = webrtc
设置完成后，我将requestIceServers-Method添加到src / web_app / js / util.js（https://github.com/webrtc/apprtc/blob/master/src/web_app/js/util.js）

function requestIceServers(iceServerRequestUrl, iceTransports) { return new Promise(function(resolve, reject) { var servers = [{ credential: "webrtc", username: "rtc", urls: [ "turn:192.168.178.20:3478?transport=udp", "turn:192.168.178.20:3478?transport=tcp" ] }]; resolve(servers); }); }

并注释掉标准方法：

//function requestIceServers(iceServerRequestUrl, iceTransports) { //return new Promise(function(resolve, reject) { //sendAsyncUrlRequest('POST', iceServerRequestUrl).then(function(response) { //var iceServerRequestResponse = parseJSON(response); //if (!iceServerRequestResponse) { //reject(Error('Error parsing response JSON: ' + response)); //return; //} //if (iceTransports !== '') { //filterIceServersUrls(iceServerRequestResponse, iceTransports); //} //trace('Retrieved ICE server information.'); //resolve(iceServerRequestResponse.iceServers); //}).catch(function(error) { //reject(Error('ICE server request error: ' + error.message)); //return; //}); //}); //}

当我现在开始我的游戏，我的转弯服务器和对撞机

python ~/google_appengine/dev_appserver.py ~/google_projects/apprtc-master/out/app_engine --host=0.0.0.0 sudo turnserver -a -r 192.168.178.20 $GOPATH/bin/collidermain -port=8089 -tls=false

我能够在两个浏览器客户端之间建立连接（从对撞机终端登录）

rtc@rtc:~$ $GOPATH/bin/collidermain -port=8089 -tls=false 2016/11/05 00:07:32 Starting collider: tls = false, port = 8089, room-server=http://rtc 2016/11/05 00:10:24 Created room stackoverflow 2016/11/05 00:10:24 Added client 97869213 to room stackoverflow 2016/11/05 00:10:24 Client 97869213 registered in room stackoverflow 2016/11/05 00:10:57 Added client 96368166 to room stackoverflow 2016/11/05 00:10:57 Client 96368166 registered in room stackoverflow 2016/11/05 00:10:57 Sent queued messages from 97869213 to 96368166 2016/11/05 00:11:09 Deregistered client 96368166 from room stackoverflow 2016/11/05 00:11:09 Removed client 96368166 from room stackoverflow 2016/11/05 00:11:19 Removing client 96368166 from room stackoverflow due to timeout

当我现在尝试通过本机应用程序连接时，我总是收到上面提到的错误。
【适用于appr.tc的原生Android应用】经过调查后，我在git上发现了以下链接，但它对我没那么帮助：https://github.com/webrtc/apprtc/issues/366
所以我决定玩constants.py（https://github.com/webrtc/apprtc/blob/master/src/app_engine/constants.py）并找到一个覆盖Turn / Stun服务器的地方

# Turn/Stun server override. This allows AppRTC to connect to turn servers # directly rather than retrieving them from an ICE server provider. TURN_SERVER_OVERRIDE = [] # Enable by uncomment below and comment out above, then specify turn and stun # servers below. #TURN_SERVER_OVERRIDE = [ #{ #"urls": [ #"turn:192.168.178.20:3478?transport=udp", #"turn:192.168.178.20:3478?transport=tcp" #], #"username": "rtc", #"credential": "webrtc" #}, #{ #"urls": [ #"stun:stun.l.google.com:19305" #] #} #]

所以我评论了TURN_SERVER_OVERRIDE = [] out，评论了我的turnserver中的其他行并填写了我的凭据，在turnserver.conf中配置
GAE意识到应用程序有新的请求。它记录

INFO2016-11-05 00:06:31,649 apprtc.py:408] Added client 50600142 in room stackoverflow, retries = 0 INFO2016-11-05 00:06:31,650 apprtc.py:92] Applying media constraints: {'video': True, 'audio': True} WARNING2016-11-05 00:06:31,653 apprtc.py:136] Invalid or no value returned from memcache, using fallback: null INFO2016-11-05 00:06:31,653 apprtc.py:551] User 50600142 joined room stackoverflow INFO2016-11-05 00:06:31,653 apprtc.py:552] Room stackoverflow has state ['50600142'] INFO2016-11-05 00:06:31,658 module.py:788] default: "POST /join/stackoverflow?wstls=false HTTP/1.1" 200 1175

但仍然会抛出同样的错误。
由于这不起作用，我试图将转向服务器地址插入ICE_SERVER_BASE_URL（仍然在constants.py中）

ICE_SERVER_BASE_URL = 'https://networktraversal.googleapis.com' ICE_SERVER_URL_TEMPLATE = '%s/v1alpha/iceconfig?key=%s' ICE_SERVER_API_KEY = os.environ.get('ICE_SERVER_API_KEY')
